Despite being only one cell, it can be huge. Despite being only one cell, it can be many. Despite being only one cell, its biological organisation has survived over a billion years. Despite being only one cell, it is amazingly smart! Physarum polycephalum, affectionately nicknamed 'The Blob', is a remarkable single-celled organism that has captivated researchers from various scientific disciplines with its unique biological traits. Remarkably, it doubles or even triples in size daily and can expand to several square meters. If cut in two, it forms two autonomous and functional individuals that can later merge back into a single organism through fusion. Moreover, it rejuvenates after a period of dormancy and can thus live for several decades. Despite its simplicity, this unicellular organism exhibits complex behaviors typically associated with more advanced life forms. It can navigate complex mazes, anticipates events, communicates with its congeners, and has the ability to learn and memorize. We measure these capabilities through its movements, themselves generated by an oscillating circulatory system. This system connects a plethora of small decision centers that communicate together to elaborate a collective response: the motion of the cell. Join us to explore how its functioning opens up new ways of looking at living things: from awesome cellular properties and tortuous network geometries to enchanting oscillations and complex behaviors. One thing is certain, the Blob is far from done surprising you! Aurèle Boussard research focuses on the behaviors of distributed living systems such as slime molds and animal groups. During his PhD, he studied the persistence of a very simple form of learning in slime moulds and supplemented this experimental ethology side with image analysis to quantify the behaviors of this unicellular. Slime molds contain an internal circulatory system allowing a plethora of small decision centers to communicate and elaborate collective responses. His research currently asks how such a collective response emerges. On the one hand, he is using a theoretical model from probability theory to study the collective accuracy of many interacting agents. On the other hand, he is using fractal geometry to bring a novel understanding on the causal links between the geometry of the circulatory system of slime molds, the patterns it generates locally, and the resulting behavior.
